Dolly, right, the first cloned sheep produced through nuclear transfer from differentiated adult sheep cells, and Polly, the world's first transgenic lamb, are in their pen in Scotland, in early December, 1997. Scientists at the Roslin Institute produced Molly and Polly cloned with a human gene so that their milk will contain a blood clotting protein that can be extracted for use in treating human hemophilia. Dr. Ian Wilmut's technique motivated many governments to ban research on human cloning. Dolly was later naturally mated and gave birth to a healthy lamb. less

In 2007 scientists said they had created the world's first cloned embryo from a monkey, in work that could spur cloning of human cells for use in medical research. They used the same method that created Dolly the Sheep and other animals. It was the first time that this technique has been successfully used to create cloned primate embryos. less
